BMW 6 Series E63/E64 (2003 - 2010) Rear Subframe Front Mounting Bush - PFR5-720BLK This is a complete replacement bush. For an insert that fits the voiding of the original bush, use PFR5-723 (except M5) - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
